Eleven years after Belle and Sebastian transformed an English seaside resort into a summer camp for indie kids, the Bowlie Weekender is back. This time, the Glasgow band are to curate December's All Tomorrow's Parties, the festival that their 1999 event inspired.

Billed as Bowlie 2, the festival will round off a year of 10th-anniversary celebrations for All Tomorrow's Parties, including weekends curated by Matt Groening and Jim Jarmusch, and full-album performances by Iggy and the Stooges and Suicide. Belle and Sebastian will curate all three nights, 10-12 December, programming dozens of bands, films and a 24-hour television channel. They will also headline at least one evening.

Back in April 1999, the Bowlie Weekender "started it all", according to ATP organisers. Stuart Murdoch and co took over Camber Sands, Sussex, and filled it with friends. The Scots came out in full force – bands such as Camera Obscura, the Pastels, Teenage Fanclub and Mogwai. But among fans and DJs like Jarvis Cocker and Steve Lamacq, there were international acts too: the Flaming Lips, Sleater-Kinney, Cornelius and even Godspeed You! Black Emperor.

The event inspired the launch of ATP, first as an annual event, then a bi-annual festival and now a several-times-annual affair. All Tomorrow's Parties was even held at the same holiday camp, until its UK operation moved to Minehead in 2006. But although ATP has since been curated by everyone from Vincent Gallo to My Bloody Valentine, Belle and Sebastian have never been back – not even as performers. Perhaps they've been too busy trying on new cardigans.

Another ATP will take place a week before Belle and Sebastian's, 3-5 December, with curators yet to be revealed. In between, ATP will hold the, er, In Between Days series of gigs for those who wish to stick around (and pay up) for both jamborees. Tickets for Bowlie 2 will go on sale Monday, when the initial lineup will also be announced. Chalet berths start at £145.

Apart from Stuart Murdoch's God Help the Girl project, Belle and Sebastian haven't released an album since 2006's The Life Pursuit. They recently announced a string of festival dates in Europe and Asia, as well as plans to record their eighth studio album in Los Angeles. Writing on the band's blog, Murdoch described the new songs' themes: "nostalgia, empathy/pedagogy, desire (non-sexual), anatomy of doomed love, lust/jealousy, anatomy of barely tasted love, empathy for a stranger, nostalgia/denial, shock of change/self assertion, desire and uncertainty, self assertion/subtle kiss-off, spiritual desire [and] spiritual affirmation." Yes, that definitely sounds like Belle and Sebastian.
